In referring to the drawings in detail like numerals designate likeparts.

The box inclosing the mechanism is divided about midway horizontallyinto two sections a lower section 1, which constitutes a reservoir forthe lubricant and an upper section 2 which serves both as a cover forthe lower member and a support for the uinping mechanism. The twosections are astened together by bolts 3 which are preferably two innumber.

The pumping mechanism is supported wholly from the upper section of thebox so that it can be quickly exposed for repair or replacement shouldit become necessary, by removing the bolts 3 and lifting the uppesect-ion from the lower section.

Thepumping mechanism is what is known as a force feed, the lubricantbeing drawn by suction into a suitable pipe and then forced through thepipe to the point requiring lubrication, and it includes a plurality offeeding, plungers and a sight glass located in the path of the feedbetween the plungers.

A tubular metal element of angular form which will hereinafter be termedthe cylinder is supported from the upper section and has an upperhorizontal member or portion v4c which extendsthrough an opening or slotin one of the vertical ends "of the upper section, a vertical portion ormember 5 depending from the upper portion 4: and a lower horizontalmember or portion 6.

The upper horizontal member 4 is in part exteriorl screw threaded and isclamped in place 1n the opening in the end of the upper section betweena shoulder 7 formed on the cylinder and'a washer 8 and nut 9.

A plurality of Valves are arranged in the outer projecting part of themember 4 and each preferably consists of cone valves 10, removablesleeves 11, having annular valve seats 12 as shown in Fig. 7 and valvetensioning springs 13. a

A pipe 14 which serves to conduct the oil to. the desired location isconnected to the outer end of the member 4.

Fig. 12 is an- In that portion of the upper member 4 is journaledtransversely in suitable bearlocated within the box and extending iniwardly from the valves, a bushing 15 is rev movably placed being securedin place by a screw ring 16, see Fig. 1.

A cup portion 17 is formed upon the up- 5 per member 4 whichcommunicates with the chamber within the bushing 15 through a itransverse opening 18, see Fig. 1.

the lower end of the vertical member and is tubular in form toconstitute a chamber 19 for a lower feeding plunger.

The opening 19 through the lower hori zontal member communicates at itsinner end with a vertical opening 20 in the lower end of the verticalmember and two ball valves are arranged in the vertical opening onebeing located above and the other below the opening 19, as shown inFigs. 1 and 13.

The upper ball valve consists of an annulus or ring 21 screwed in thevertical opening 20 and having a valve seat 22, a ball 23 arranged abovethe seat 22 and a spiral tensioning spring 24k in the vertical opening20 above the ball 23; and the lower ball valve comprises a tubular plug25 screwed in the lower end of the vertical opening 20 and having avalve seat 26, a ball 27 located above the seat 26 and a spiraltensioning spring 28 arranged between the ball and the ring 21 of theupper valve, see Fig. 13.

From the upper termination of the vertical opening 20, a shorthorizontal opening 29 extends in a lateral enlargement 30 of thevertical member to a vertical opening 31. The vertical opening 31extends upward through the top of the lateral enlargement 30 and avertical pipe 32 has its lower end fitted in said opening 31. The upperextremity of the pipe 32 extends through an opening 33 in the top of theupper section of the box and is bent upon itself to form a goose neck 34which is vertically over the cup 17. A dome is erected over the gooseneck which consists "of a circular ring of glass or other transparentmaterial 35 and a top cap 36 provided with depending legs'37 whichextend downward on the outside of t are fitted to secure the cap to theupper section of the box.

A lower feeding plunger 39 is slidably fitted in the opening 19 in thelower horizontal member and an upper feeding plunger 40 is slidablyfitted in the opening in the bushing 15 in theupper member 4. The upperplunger is preferably of larger diameter than the lower plunger so as tohave a greater feeding capacity. Both of the plungers are reciprocatedfrom a shaft 41 which ings in the upper section of the inclosing box,and said shaft has a projecting end upon which a ratchet wheel 42 isll'lOLllllLQCl. An arm 43 has a collar l4.- at. its inner end which ismounted on the shaft 41 and a spring tensioned pawl 45 at its outer endwhich engages with the ratchet wheel. A rod &3 which is actuated fromsome movable portion of the machinery requiring lubrication is connectedto the arm 43 to rock the same and thereby impartan intermittent rotarymovement to the shaft: An eccentric 46 is mounted on the shaft 41 and aneccentric strap 47 which is preferably in the form of the letter U issecured tothe inner end of the upper plunger el-O and partially sur- Alongitudinally extending regulating screw 48 is rotatably rounds theeccentric 46.

mounted in the end of the upper section of the box opposite the endthrough which the lock nut to prevent involuntary rotation of theregulating screw in the spool. The outer end of the strap 47 isbifurcated as shown at 51 in Fig. 3 and the spool is fitted between theforks. An angular arm 52 has a'collar at its upper end which is looselymounted 1 by split pins, as shown in Figs. 5 and 9; and

a bifurcated lower end 55, the forks of which extend upon opposite sidesof the lowerplunger and between two flanges 56 on the lower plunger asshown in Figs. 2 and 11. Y

The reservoir is filled through an opening 57 in the top of the uppersection at one side of the dome. A cover 58 is hinged to the top andserves to close the opening 57, and said cover is locked in place whenclosed by a bent spring finger 59, see Fig. 5. A wire screen 60 isplaced over the opening 57 below the cover 58 and the usual filteringcup 61 depends from the screen as shown in Fig. 5.

A device for indicating the amount-of oil in the reservoir is providedin the lower section of the box which consists of :1 vertical slot 62formed in one of the sides of ,said lower member and constituting a viewThe lower section or reservoir of the box is provided with a heatingchamber 65 for the purpose of warming the oil so that it will flowfreely in cold Weather or in frigid countries, which is formed by coringout a portion of the bottom of the box and connecting the chamber soformed to any suitable source of heat such as steam or hot air:

The operation of this improved force feed lubricator is as follows Bothof the plungers being reciprocated back and forth from the eccentric onthe shaft, the oil is drawn through the lower ball valve by the suctionstroke of the lower plunger into the opening in the lower horizontalmember and then forced upward through the upper ball valve to andthrough the goose neck pipe from which it drops through the sight domeinto thecup. Passing through the opening in the bottom of the cup 1tflows into the chamber in which the upper plunger 15 lorated and isforced from said chamber.

through the double cone valves into the pipe extending to the pointrequiring lubrication. trolled by the regulating screw. the turning ofwhich moves it longitudinally in its supporting sleeve, and changes theposition of the angular arm and through saidarm the feeding position ofthe lower plunger. An overflow opening (it; is formed in the lowerhorizontal member as shown in Fig. 13 and the volume of oil fed at eachforcing stroke of the lower plunger is regulated by the length of thefeeding stroke of the plunger beyond the over-flow opening, as the oildrawn into the chamber in front of the plunger by the suction strokepasses out through the overflow opening during the fore part of theforce stroke until the end -of the plunger passes over said opening.

' Thefeeding of the oil it will be thus noted does not begin on theforce stroke of the plunger until the plunger passes over and closestheoverflow opening 66. The stroke of the upper plunger is not varied orchanged as it is not-necessary as it always has a greater feedingcapacity than. the lower plunger so that the sight dome cannot fill withoil. The entire cylinder complete with the eccentric strap and gooseneck pipe can be removed bodily from the upper section when said sectionis separate from the lower section by simply loosening the nut 9, andlifting the upper section together with the shaft and the regulatingscrew from the cylinder. This enables the machine to be quickly andcompletely dismounted and the entire cylinder mechanism to be whollyexposed. Owing to the improved construction the lower plunger togetherwith the lower portion of the cylinder is submerged in the. oil in thereservoir portion of the box, being located completely beneath thesurface of the oil so that when the reservoir is filled no air can bepumped and the pumping action is both uniform and positive. The angular.arm 52 in operating the lower plunger moves to and fro in the Theregulation of the feed is con-v oil and tends to agitate or stir thesame keeping it at. a constant level which is a great advantage withheavy slow flowing oil especially when the oil is nearly exhausted andthe level in the reservoir is near the bottom aspit prevents the suctionaction of the pumpingmechanism lowering the level near illBiYtllYGentrance sufficiently tosuck in air.,
